Women's floor routines are the most visibly artistic of all the events, as they include custom music and usually allow for a lot of personality to shine through. Routines consist of tumbling passes and series of dance elements like jumps and leaps, among other skills. A gymnast can perform up to four tumbling passes (at the top tier of senior-level competition, three or four tumbling passes are required), which often include at least one flight element. Deductions can occur for not using the whole mat, for making technical errors, and, oddly, for having lyrics in their music.
